Abstract
A coupling facility is coupled to one or more other coupling facilities via one or more peer links. The coupling of the facilities enables various functions to be supported, including the duplexing of structures of the coupling facilities. Duplexing is performed on a structure basis, and thus, a coupling facility may include duplexed structures, as well as non-duplexed or simplexed structures.
Claims47
A method of coupling a plurality of coupling facilities of a computing environment, said method comprising:
- selecting a first coupling facility and a second coupling facility to be coupled;
- and
- providing at least one peer connection between the first coupling facility and the second coupling facility to couple the first coupling facility and the second coupling facility.
A method of coupling a plurality of coupling facilities of a computing environment, said method comprising:
- selecting a plurality of coupling facilities to be coupled;
- and
- providing at least one peer connection between the plurality of coupling facilities.
A system of coupling a plurality of coupling facilities of a computing environment, said system comprising:
- a first coupling facility and a second coupling facility to be coupled;
- and
- at least one peer connection between the first coupling facility and the second coupling facility to couple the first coupling facility and the second coupling facility.
A system of coupling a plurality of coupling facilities of a computing environment, said system comprising:
- a plurality of coupling facilities to be coupled;
- and
- at least one peer connection between the plurality of coupling facilities.
A system of coupling a plurality of Coupling facilities of a computing environment, said system comprising:
- means for selecting a first coupling facility and a second coupling facility to be coupled;
- and
- means for providing at least one peer connection between the first coupling facility and the second coupling facility to couple the first coupling facility and the second coupling facility.
A system of coupling a plurality of coupling facilities of a computing environment, said system comprising:
- means for selecting a plurality of coupling facilities to be coupled;
- and
- means for providing at least one peer connection between the plurality of coupling facilities.
At least one program storage device readable by a machine tangibly embodying at least one program of instructions executable by the machine to perform a method of coupling a plurality-of coupling facilities of a computing environment, said method comprising:
- selecting a first coupling facility and a second coupling facility to be coupled;
- and
- providing at least one peer connection between the first coupling facility and the second coupling facility to couple the first coupling facility and the second coupling facility.
At least one program storage device readable by a machine tangibly embodying at least one program of instructions executable by the machine to perform a method of coupling a plurality of coupling facilities of a computing environment, said method comprising:
- selecting a plurality of coupling facilities to be coupled;
